MANDREL-PRESS.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed June 19, 1920. Serial No. 390,276.

T 0 all w 710m it may concern:

Be it known that I, Bonner W.TAYL0R, S12, a citizen of the UnitedStates, residing in the city and county of Kalamazoo and State ofMichigan, have invented certain new and useful Improvements inMandrel-Presses, of which the following is a specification.

This invention relates to improvements in mandrel presses.

The main objects to this invention are to provide in a mandrel press animproved work table which may be quickly and easily adjusted to work ofdifferent kinds and sizes and'at the same time one which is very strongand rigid.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a rear perspective view of a mandrel press embodying thefeatures of my invention.

Fig. II is a horizontal section on a line corresponding to line 2-2 ofFig. Ibut with the main table members shown in full lines in operativeposition and by dotted lines in inoperative position.

Fig. III is a similar horizontal section showing the table members inanother adjustment by full lines and still another adjustment by dottedlines.

Fig. IV is a similar horizontal section with the auxiliary table membershown in operative position by full lines and in inoperative position bydotted lines.

In the drawing similar reference characters refer to similar partsthroughout the several views.

Referring to the drawing, the frame comprises the base 1, uprights 2, 2and 3 supporting the top plate 4. The uprights are supported intriangular position upon the base with the upright 3 at the rear. Thetop plate constitutes a support for the ram 5 and its driving mechanismwhich is pro vided with a gear housing 6. The driving means for the ramare not illustrated or de scribed in detail as they form no part of thisinventlon. The mechanism is preferably that, however, shown anddescribed in detail in the U. S. Letters Patent to Frank Burtt,

Patent No. 1,356,905, dated October 26, 1920, my improvements beingcommercially embodied in machines having the features 9 when the tablemembers are adjusted to operative position. The table members havecoacting top portions 10 eccentric relative to their axis and spacedfrom the base so that the spaces may be varied by swinging the membersthus adapting them to receive arbors of different diameters.

The table members 7 may be swung to inoperative position and entirelyout of the way as shown in dotted lines in Fig. II.

I also preferably provide an auxiliary table member 11 pivoted upon oneof the uprights 2 and adapted to swing over and rest upon the topportions 10 of the main table members 7. The table member 11 has avertical channel 12 which is alined with the spaces between the topportions of the table members 10,. A work holder 13 having openings 14of different sizes adapted to be brought over the channel 12 isrotatably mounted on the table member 11.

I'Vith this arrangement of parts the table member may be quicklyadjusted to adapt them to the particular work and they are very strongand rigid.

I have not attempted to illustrate certain adaptions and modificationswhich I contemplate as I believe the disclosure made will enable thoseskilled in the art to which my invention relates to embody or adapt thesame as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a mandrel press, the combination of a frame comprising a base anda pair of uprights, a pair of main table members journaled on saiduprights to be swung to operative position over said base and providedwith foot portions resting on the base when in operative position andwith coacting top portions eccentric. relative to their axes and spacedfrom said base so that the spaces between them may be varied by swingingthe members, an auxiliary table member pivotally mounted on one of saiduprights to be swung over and rest upon the top portions of said maintable members,

said auxiliary table member being provided. with a vertical work channeladapted to be alined with the space between the top portions of saidmain table members, and a i be varied by swinging the members, an aux--iliary table member pivotally mounted on one of said uprights to beswung over and rest upon the top of portions of said main table members,said auxiliary table member being provided with a vertical work channeladapted to be alined with the space between the top portions of saidmain table members.

3. In a mandrel press, the combination of a frame comprls ng a base anda pair of uprights a pair of table members journaled 30 on said uprightsto be swung to operative position over said base and provided with footportions. resting on the base when 'in operative position and withooacting top portions eccentric relative to their axes and 35 spacedfrom said base, so that the space be tween them may be Varied byswinging the members.

4. In amandrel press, the combination of a frame comprising a base and apair of up 40 rights, a pair of table members journaled on said uprightsto be swung to operative position over said base and provided with coacting top portions eccentric relative to their axes and spaced fromsaid base, s04

that the space between them may be varied by swinging themembers.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses.
